'Dead zone' volume more important than area to fish, fisheries

Dubravko Justic, the Texaco Distinguished Professor in the LSU Department of Oceanography & Coastal Sciences, and Research Associate Lixia Wang recently co-authored a study suggesting that measuring the volume rather than ...

Reconstructing past oxygen minimums with an eye to the future

A recent paper published in PLOS ONE uses geochemical and fossil evidence from the period of global warming at the end of the last ice age to reconstruct the depth and extent of ocean areas with dissolved oxygen below those ...

How do scientists predict the size of an oceanic 'dead zone'?

Later this month, NOAA will announce its prediction for how big the hypoxic "dead zone" will be in the Gulf of Mexico. This year the forecast will be based on an ensemble that incorporates the results of four different computer ...

Scientists tackling Gulf of Mexico hypoxia

Bouncing along the edge of a field, Larry Berry points across the pasture toward a tree line marking the path of a creek bed. A small plastic shed sits atop a wooden platform on stilts.

Researchers suggest plan to address hypoxia in Gulf of Mexico

Despite a 12-year action plan calling for reducing the hypoxia zone in the Gulf of Mexico, little progress has been made, and there is no evidence that nutrient loading to the Gulf has decreased during this period. University ...

Lower nitrogen losses with perennial biofuel crops

Perennial biofuel crops such as miscanthus, whose high yields have led them to be considered an eventual alternative to corn in producing ethanol, are now shown to have another beneficial characteristic–the ability to reduce ...

Researcher: Smaller 'dead zone' recorded in Gulf

A new report says this year's Gulf of Mexico "dead zone," an area of low oxygen that develops every spring and summer, is the fourth-smallest since measurements of the zones began in 1985.
